Just like the outer shell, the inner shell, typically made of EPS (expanded polystyrene), is built to absorb impacts. As it is in near-contact with the head, the inner shell needs to be softer so that it itself does not damage the head when absorbing an impact. Lazer typically uses a triple-density construction, so as to bring an optimal phasing in the absorption process, with denser EPS against the shell and looser EPS against the head. Again, just like with the outer shell, we want to create a gradual fracturing process, with consecutive yielding points.
